【摘要】 本文介绍了测量节理表面形貌的RSP-Ⅰ型智能岩石表面形貌仪,分析了节理表面的形貌特征,对表面形貌中的随机不规则度分量和波纹度分量作了区分,并研究了它们对节理剪切性质的不同效应,提出了含波纹度节理的剪切强度公式并用直剪试验确定了其中的参数,试验结果和理论分析证实了该剪切强度公式比以前的相应公式更能反应节理面剪切的力学行为。更多还原

【Abstract】 RSP-1 type intellegent profilometer of rock suface used for measuring suface topography of joints is introduced on this paper.According to a large number of measuring results the topographic characteristic of joint surfaces are analyzed.Random irregularity component and waviness component arc separated and different effects on shear property of joint of those components are studied.The formula of shear strength of joint containing waviness is put forward and corresponding parameters are determined by direct shear test of joint.It is verified by test results and theortical analysis that the new shear strength formula can reflect shear mechanical behaviour of joint better than former corresponding formula.更多还原
